SEAT-MOUNTING FOR AGRICULTURAL IMPLEMENTS.

To all whom it may concern:

Be it known that I, HOWARD T. INGHIIAM, citizen of the United States, residing at Fail-field, in the county of Jefferson and State of Iowa, have invented certain new and useful Improvements in Seat-Mountings for Agricultural Implements, of which the following is a specification.

This invention relates to shock absorbers for riding cultivators, harrows and the like and has for its object to provide means for yieldably supporting the drivers seat on the cultivator frame, thereby to absorb any shock or ar imparted to the cultivator when the latter is traveling over rough, uneven ground, or strik s an obstruction in the path of travel.

A further object is to provide a shock absorber capable of being quickly attached to any type of riding agricultural implement or machine and which will respond instantly to all shocks incident to the operation of the machine, thus insuring comfort to the driver regardless of surface conditions.

A further object is to provide a shock absorber including a tubular member or sleeve for attachment to the axle or other fixed portion of a cultivator frame and having an angular lever pivotally mounted thereon and adapted to receive and support the drivers seat, suitable springs being operatively connected with the lever for yield ably supporting the seat in normal position.

A still further object of the invention is generally to improve this classof devices so as to increase their utility, durability and etliciency.

Further objects and-advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

F or a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a shock absorber constructed in accordance with my invention, the same being shown attached to a cultivator; Fig. 2 is an enlarged side elevation partly in section; Fig. 3 is a rear view; Fig. i is a bottom plan view.

Corresponding and like parts are referred to in the following description and indi- Specification of Letters Patent.

cated in all the views of the drawings by the same reference characters.

The device comprises a tubular casting or sleeve 5 adapted to telescope the axle or other fixed portion of a cultivator frame, indicated at (5, said sleeve being provided with spaced depending ears 7 having transversely alined perforations formed therein and constituting bearings for the laterally extending trunnions S of an angular lever 9. The short end of the lever 9 extends beneath the sleeve 5, while the long end thereof projects above the top of said sleeve and is provided with an integral horizontally disposed plate 10 adapted to receive and support a strap 11 on which is mounted a drivers seat, indicated at 1 Projecting vertically from the plate 10 is a centrally disposed forwardly inclined lug 13 which enters an opening let formed in the adjacent end of the seat strap 11 and serves to center the strap on the supporting plate 10, there being an overhanging lug 15 projecting vertically from one side of the plate 10 and adapted to bear against the upper edge of the strap 11 to assist in preventing accidental displacement of said strap.

The lever 9 is reinforced and strengthened by the provision of a rib 16, which latter preferably extends the entire length of the bell crank lever and also extends beneath the supporting plate 10. An auxiliary strengthening rib or web 17 is formed on the lever and extends beneath the supporting plate 10 at right angles to the rib l8. Extending laterally from the upper end of the lever 9 is an eye 19 which receives an eye 20 on the adjacent end of a downwardly inclined rod 21, the opposite end of said rod being extended through a guiding eye or loop 22 extending vertically from the top of the sleeve 5 and is provided with terminal threads 2-3 for engagement with an adjusting nut 24.. Interposed between the nut 24 and the guiding eye or loop 22, is a coil spring 25 which serves to yieldably support the long arm of the lever in engagement with the adjacent side of the sleeve 5. The short arm of the lever 9 is extended laterally at the base of said sleeve 5 to form an eye 26 in which is seated a vertically disposed arcuate rod 27. The upper end of the rod 27 is provided with a hooked terminal 28 which engages an ear or projection 29 extending laterally from one side of the sleeve 5, while the lower end of the rod is threaded at 30 for engagement with a correspondingly threaded adjusting nut 31. A coil spring 32 is interposed between the nut 31 and the lower face of the eye 26, thereby to assist in supporting the plate 10 and drivers seat in normal position.

The tubular member or sleeve 5 is retained in position on the axle or other fixed portion 6 of the cultivator frame by means of a set screw 33, which latter extends through a threaded boss 34 formed on the base of the sleeve 5 for engagement with the axle 6. The opposite ends of the sleeve 5 are preferably strengthened by reinforcing ribs 35, which latter entirely surround the opposite ends of the sleeve, as shown. Thus it will be seen that should the cultivator strike a stone or other obstruction in the path of travel, the shock incident to the impact of the cultivator with said obstruction will he received and absorbed by the springs 25 and 32 so as to prevent the shock or jar from being transmitted to the drivers seat. It will here be noted that when the cultivator strikes an obstruction, the lever 9 will have a tendency to swing downwardly on its pivotal axis 8 and against the tension of the spring 25, the eye 26, by engagement with the spring 32 at the same time serving to com press the latter and thus absorb any jar or shock which would otherwise be transmitted to the drivers seat. By rotating the nuts 21 and 31, the tension of the springs 25 and 32 may be regulated at will.

' The device is extremely simple in construction and may be attached to any style of cultivator or other riding agricultural machine, without necessitating any change in the construction thereof.

Having thus described the invention, what is claimed as new is:

1. The combination with a support, of a horizontally disposed sleeve adjustable longitudinally of the support, a seat supporting lever pivotally mounted on the sleeve, means operatively connected with the seat supporting lever for yieldably holding the latter in normal position, and means for holding the sleeve in adjusted position on said support.
